The right-wing blogger who organized the 'Draw Muhammad' event that was targeted by two gunmen over the weekend has had a fierce TV confrontation with a hate preacher, who thinks she should receive capital punishment.

Host Sean Hannity then reminds his viewers what Choudary believes in - which is imposing Sharia law across all countries, including America.

The controversial imam then says: 'Let's be clear we are not talking about Mickey Mouse or Donald Duck. We are talking about people who deliberately had a competition to insult the messenger Muhammad.

'If you saw the cartoons that Charlie Hebdo drew, you would understand the anger.'

Rabble rouser Choudary, who once said 'the flag of Islam will fly over the White House', then goes on to talk about how Geller was fully aware that many Muslims consider blasphemy a crime that is worthy of the death penalty.

The head of the American Freedom Defense Initiative then tries to get Choudary to stop interrupting her, and at one point says: 'I know you're used to stepping over women.'

Choudary then says Geller is worse than a 'Khanzier'- Arabic for pig - and starts ranting about Americans murdering innocent people, prompting Hannity to intervene.

He ends the conversation by saying the cleric is 'evil and pathetic.'

Geller, who has received death threats since the art event, began by claiming President Obama has 'created an environment that raised the stakes' on terror in the United States

The Southern Poverty Law Center, who have designated Geller's AFDI a hate group, condemned the appearance of the pair in an email to the Media Matters blog.

Heidi Beirich, the director of the SPLC's Intelligence Project, wrote: 'We're disappointed, but not entirely surprised, that Sean Hannity would offer a national platform to two well-known haters. Ms. Geller and Mr. Choudary represent nothing more than an extreme political fringe.

'Their divisive behavior is made even worse by the fact that Ms. Geller is now positioning herself to be a defender of free speech, while Mr. Choudary is purporting to speak on behalf of all Muslims.'

ISIS quickly moved to claim the attack as its own and has now issued a terrifying death threat aimed at Geller, as well as claiming to have 71 'trained soldiers' operating within America.

Geller has since expanded her security team in the wake of the death threat she received after the attack and has been in contact with the NYPD's counter-terrorism unit.

It extended the warning to anyone who dared host her events or give her a platform to 'spill her filth'. The message claimed this would make them 'legitimate targets'.

A message posted online read that the weekend's attack was only the beginning of ISIS' 'efforts to establish a wilayah [province] in the heart of our enemy'.

It went on: 'Our aim was the khanzeer Pamela Geller and to show her that we don't care what land she hides in or what sky shields her; we will send all our Lions to achieve her slaughter.'

NYPD spokesman Stephen Davis says the threat named Geller specifically. He says investigators from counterterrorism and intelligence bureaus met with her Wednesday and will do a 'comprehensive threat assessment' to decide whether it's credible enough to require security for Geller.

Choudary started to go on rants about Americans murdering innocent people before host Sean Hannity branded him as 'pathetic and evil'

Geller has hinted that she held the event in response to killings in Paris over the public depiction of the Muslim prophet Muhammad, whom Islam dictates must never be drawn or painted.

Through websites, books, ad campaigns and public events, Geller has been warning for years about the 'Islamic machine' that she says threatens to destroy the U.S.

She famously led the campaign in 2010 — under a different group, called Stop the Islamization of America — to prevent the opening of an Islamic community center blocks from the World Trade Center site. She called it the 'Ground Zero Mosque.'

The Southern Poverty Law Center, a nonprofit organization that tracks hate groups, keeps a dossier on her in its 'extremist files,' calling her 'the anti-Muslim movement's most visible and flamboyant figurehead.'

The law center describes her as 'relentlessly shrill and coarse in her broad-brush denunciations of Islam' and notes some of her more sensational claims, including that President Barack Obama is the 'love child' of Malcolm X.

'I don't think that many Westernized Muslims know when they pray five times a day that they're cursing Christians and Jews five times a day,' she was quoted as telling The New York Times in 2010. She also said: 'I believe in the idea of a moderate Muslim. I do not believe in the idea of a moderate Islam.'

The weekend contest in Garland, Texas, was offering $10,000 for the best cartoon of Muhammad.

Choudary is currently on bail in the UK for allegedly being a member of a banned terrorist group. He founded the organization Al-Muhajiroun 20 years ago and is seen as a recruiting sergeant for Britain's radical Muslims.

He has previously called Americans 'the biggest criminals in the world today.'

He hit U.S. headlines in 2011 after a furious exchange with Hannity on Fox News. The presenter became so enraged with his anti-American comments he ended the interview by calling him a 'sick, miserable, evil S.O.B'.
